10 days after infection with CVB3 WT mice show a significantly increased mRNA expression level of the proinflammatory cytokines IL-1β (15.92 ± 5.86 fold, P = 0.0043), IL-6 (18.62 ± 8.89 fold, P = 0.0043), and TNF-α (8.85 ± 3.34 fold, P = 0.0043) compared to the expression level in cardiac tissue of untreated WT mice. Here, IL1B is linked to infection.
